Method Detail

get

public static TaskDispatcher get()

Accessor for the current TaskDispatcher.

Returns:

The current TaskDispatcher.

get

public static TaskDispatcher get(ServerContext ctx)

Accessor for the current TaskDispatcher in more complex setups. For some setups DWR may not be able to discover the correct environment (i.e. ServletContext), so we need to tell it. This generally happens if you have DWR configured twice in a single context. Unless you are writing code that someone else will configure, it is probably safe to use the simpler get() method.

Parameters:

ctx - The servlet context to allow us to bootstrap

Returns:

The current TaskDispatcher.

attach

public static TaskDispatcher attach(Container container)

Internal method to allow us to get the Builder from which we will get TaskDispatcher objects. Do NOT call this method from outside of DWR.
